在同一页面中导航锚标记时关闭向左滑动菜单?
Close Slide-Left Menu when navigating anchor tags in the same page?
当我切换打开左滑菜单和select锚标记link时,它导航到同一页面上的锚定部分,但菜单保持打开状态。
我想要一个简单的 javascript 功能来关闭切换菜单,每次我点击一个锚 link 并导航到想要的部分

我已经尝试了我在堆栈溢出时发现的所有其他解决方案,包括:
$('#menu li').on('click', function(){
$("#menu").hide();
$("#menu-icon").removeClass("active");
});
但似乎没有任何效果,我在 Javascript 方面仍然是新手,因此非常感谢任何帮助或推动正确的方向。

我将此代码添加到您的底部 JavaScript:
// Find all menu links
var navLinks = document.querySelectorAll('.c-menu__link');
// For each menu link
var index = 0, length = navLinks.length;
for ( ; index < length; index++) {
// Attach click event, on click call close function
navLinks[index].addEventListener('click',
function () {
slideLeft.close();
}
);
}
Fiddle: https://jsfiddle.net/trsjL9th/3/
基本上通过 class 找到菜单中的所有链接,并附加一个调用菜单关闭功能的点击事件。
将 ID 添加到 link:
<li class="c-menu__item"><a href="#about" id="about-link" class="c-menu__link">about</a></li>
JavaScript 添加一个 onclick 侦听器:
document.getElementById('about-link').addEventListener('click', function(e) {
e.preventDefault;
slideLeft.close();
});
根据需要重复其他 ID。我发现这是最 easily-readable 的代码,当有人在 1-2 年后审查代码时,但是 YMMV。
当我切换打开左滑菜单和select锚标记link时,它导航到同一页面上的锚定部分,但菜单保持打开状态。
我想要一个简单的 javascript 功能来关闭切换菜单,每次我点击一个锚 link 并导航到想要的部分

function () {
slideLeft.close();
}
);
}
Fiddle: https://jsfiddle.net/trsjL9th/3/
基本上通过 class 找到菜单中的所有链接,并附加一个调用菜单关闭功能的点击事件。
将 ID 添加到 link:
<li class="c-menu__item"><a href="#about" id="about-link" class="c-menu__link">about</a></li>
JavaScript 添加一个 onclick 侦听器:
document.getElementById('about-link').addEventListener('click', function(e) {
e.preventDefault;
slideLeft.close();
});
根据需要重复其他 ID。我发现这是最 easily-readable 的代码,当有人在 1-2 年后审查代码时,但是 YMMV。
